Great idea!

[@joshuabaguma9100]

i just love ur biology

[@ellawalters2536]

Im not sure if you noticed but at around 28:40 you said that GPP = NPP - R but its the other way round and the question asked for NPP

[@mrhowebiology7667]

Good spot! I’ll add a banner to correct it 😄

[@qasimkhan34]

great video but doesnt include nitrogen and phosporus cycle or eutrphication

[@carafarrin339]

28 minutes in. i thought it was NPP=GPP-R. therefore NPP+R would be GPP. am i wrong?

[@carafarrin339]

just seen the commment below

[@mrhowebiology7667]

Hi you are right NPP = GPP - R

[@tiashadey-krishnan9629]

is this paper 1 or paper 2 content?

[@sarajan6690]
